295/40R22

About 295/40R22
295/40R22 is less common as a factory fitment but is available as an aftermarket size, so SKU selection is narrower than mainstream OEM sizes. At 31.29″ overall diameter, 295/40R22 turns 645 revolutions per mile, which is the reference point the factory speedometer and odometer were calibrated against. The 40% aspect ratio gives it a low-profile sidewall that delivers sharp steering response but transmits road imperfections. The 22″ rim pairing is typical for heavy-duty, off-road-lifted, and show-build applications, so compatible wheels are easy to source new or used. Going one step shorter to 285/40R22 drops diameter by 1.01%, which stays within the ±3% fitment safe zone for most vehicles. Stepping up to 275/45R22 adds 1.45% diameter — also inside the safe window, with marginally taller ride height. If you are shopping for a direct replacement, any tire within roughly ±0.7″ of the 31.29″ stock diameter (about ±2% in percentage terms) will keep ABS, TPMS, and odometer readings inside the vehicle's designed tolerance.
